DEVICE FOR SECURING SPLIT-BOLTS.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed June 27 1907- Serial No. 381050- To all whomt't may concern:

Be it known that I, JACOB J. SOUDER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Devices for Securing Split Bolts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates primarily to threadless or split bolts, such as shown and described in Letters Patent of the United States, #836,786 granted to me on the 27th day of November, 1906, and in my application for a patent for metal joints, Serial Number 361,850, filed March 11th, 1907, has especial reference to means for bending the ends of the bolt over the key or wedge in a nut or other member provided with an opening or seat to receive the boltand a key, and to swage the ends of the split bolt over the key, to effectually secure the bolt in position.

The invention has for its object efliciency, speed and economy in the bending and ,swaging of the ends of such bolts, and consists in certain features of construction, which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specificationz Figure 1 represents a vertical section partly in side elevation of a device embodying my inven-' .tion.

Fig. 2 an elevation of one of the jaws of the device. Fig. 3 a like view of the opposite jaw. Fig. 4 a side view of the thread- .ed bolt detached. Fig. 5 a like view of the ratchet lever for. operating the bolt. Fig. 6

a horizontal transverse section showing a bolt before the ends are bent and swaged, and Fig. 7 a like view of the same after the ends of the bolt have been bent and swaged.

3 and 5 are pivotally connected by a'pin 7. j

The jaw 1 is provided with an elongated swaging-cavity 8 whose end walls 9, 9 are converging to engage the separated ends 10,

10 of the bolt 11, and bend them inward toward each other and over the key 12, and

swage the ends and .draw the bolt tight against its head 13.

14, 14 are slots or grooves in the side walls of the cavity 8 to engage the edges of the key 12 and hold it while being inserted and forced between the ends 10 of the bolt 11.

The jaw 2 is provided with a circular cavity 15 to engage the head 13 of the bolt while the ends 10 of the bolt are being bent inward and swaged, and with a laterally projecting flange 16, which forms a support for the device, and rests upon the top of the head 17 of a rail-road rail while in operation to sccurethe fish-plates 18, 18 to the rail. In the jaw 1 is a left-hand screw-threaded opening 19, and in the aw 2 is a like righthand screw-threaded opening 20.

21 is a bolt having left screw-threads 22 to engage the opening 19, and right screw threads 23 to engage the opening 20, and between the oppositely screw-threaded memhers is a cylindrical head 24, in which are openings or recesses 25, and a concentric.

groove 26, engaged respectively by a retractable pin 27 and a screw 28 in the head 29 of a lever 30, the former serving as a lock to engage the lever with the head 24 of the bolt, and the latter as means to prevent the lever moving laterally. on the head. The pin 27 is drawn out of the recess 25 by a rod 31, and automatically pressed into' the recess by a spring 32, when it is desired to change the position of the lever 30 on the head 24 of the bolt. At the upper end of the jaw 1 are lugs 33 engaged by link 3 and pin 4, and on the and pin 6.

In the operation of the device, the jaws 1,

2 are drawn toward each other and separated by the bolt 21, and through their jointed connection with the links 3 and 5 and the jointed connection between the links move laterally in the same horizontal plane, to engage and disengage opposite ends of the bolt, and the jaw 1 is drawn up against the ends 10 of the bolt 11 with such force as to first insert the key 12, bend the ends 10 and then effectually swage them and draw the head of the bolt tight to its seat on the fish-plate.

It is obvious that changes in details of construction of the device, may be made without departing from the spirit of my invention,

so long as the swaging-j aw 1 is laterally movable and pressure applied thereto to bend the ends of the bolt and swage them.

Having thus fully described my invention, what I claim is 1. A device of the class described, com prising a pair of jaws, one of which is laterally movable and provided with a swagingcavity, and a right and left screw-threaded member engaging both jaws.

2. A device of the class described, comprising a pair of jaws, one of which is pivotally supported and laterally movable and provided with a swaging-cavity and means for engaging a key, and a right and left screwthreaded member engaging both jaws.
